[Samba] eventlog functionality

[ray klassen]

 so I sent you the dump separately. and i tried a persistent drive mapping to \\DC\netlogon which I figured should create a more permanent session as you described. That worked the same.

That still assumes the appliance is reading the same type of event log
(because the eventlog RPC service was superseeded by eventlog6 and the
WMI thin, which is the reason I asked for details).

If you could get the exact details on that, or the capture file if not
confidential, that would be good.

Note however that the Samba AD DC doesn't have a persistent connection
from the client unless you mount a share, so even if it worked it
wouldn't show up all the clients reliably. 

(A domain login to AD can be done with just a kerberos ticket
exchange).
